This invention relates to certain novel improvements in window latches and has for its principal vobject the provision of an improved construction of this character which will be highly efficient in use and economical in manufacture.

Among the objects of my invention is to provide a device which may be used to latch windows and similar devices` which will be 0 arranged such that it may be moved from operative position when such a movement is desirable.

Another object of the invention is to arrange a device of the foregoing character 15 suchthat the latched members may be moved a predetermined distance. n v

Another object ofrtherinvention is to arrange a device of the foregoing character in such a manner that it will bearranged such 20 that the parts will be disposedin a position which will be readily visible so as to indicate the condition of the latch. y

Other objects will appear hereinafter.

The invention consists inthe novel combi- 25 nation and arrangement of partsnto/be herev inafter described and claimed.

"The invention .will` be best understood by reference tothe accompanyingA drawings, showing the preferred form `of construction 30 and in whichz .A

' In the drawings, wherein the preferred embodiment of myinvention is illustrated, indicates the lower sash of a windowiconstruction and 11 indicates the upperV sash thereof and thesev sasheslare arranged vfor sliding'movement in vertical planes and are disposed out of alignment with eachother, the lower sash beingfdisposed' inwardly to- 1928.

ward the room as is well understood in the art.

My improved latching device includes a' i and a pintle 17 extends through suitable openings in these ears so as to hingedly connect the main body portion 12 to the leaf 15. The upper edge of the upper frame of the sash 10 embodies a recess 18 into which the leaf 15 is fitted and which is secured therein in any approved manner as by the wood screws 19. The main body portion 10 is arranged to include a housing 2O which is preferably hollow and the housingincludes a wall 21 which is adapted to terminate in engagement with the upper edge of the lower frame member of the sash 11 as is clearly indicated in Fig. 2 and therefore the end of the wall 21 and the bottom edge ofthe portion 13 will be disposed in alignment when the sash frames are aligned as is understood in the art. Mounted on the upper edge of the lower frame member of the sash 11 is a'lclamp mem# ber 22 which is secured to said frame member in vany approved `manner as *by the wood screws 23. The member 22 includes .an upwardly protruding portion 24 which has ears 25 provided on the upper edge thereof. .The clamping member 22 is adaptedlto be dis- -posed within the'housing 20' as is best illustrated in Figs. 2 and 3.v Extending across the yhousing 2O transversely to the portion '13 is a slotz25 and as is best illustrated in Fig. 3, the portion of the slot disposed inthe wall 26fof the housing 2O is closed by aiportion V27. In substantiallythe ymid-point of the portion of the slot 25 arranged inthe upper wal1r28 of the housing 20, the slot 25 is enlarged as indicated at 29 so as to provide a substantially `circular opening.. It is apparenty thatY the slot 25 extends across the housing and w divides said housing into two sections, save for the portion 27 which serves to interconneet these two sections of the-housing. l

Pivotally secured :to the ears 25 is the reduced portionA 30 ofthe substantially cylindrical rod 31, said reduced portion defining shoulders 32 on said rod. Adj acentthe shoulders 32 and adapted to extend into the reduced portion 30 isa recess 33, the utility of which will be made apparent presently. On the upper side 28 of the housing 20, an arm 34 is pivotally mounted on one side-of the slot 25 and on the opposite side of the slot 25k on the side 28, a lug I35 is mounted whichis arranged so as to retain the pivotally mounted arm 34 when it is disposed across said slot 25.

After the device has been mounted in the manner hereinbefore described, the arm 31 is disposed so that the reduced portion 30 thereof will be arranged in the portion 36 of the slot 25 and the arm 34 is disposed so as to be out of position above the slot 25, a pin 37 being provided on the upper side 2S to limit this retracting movement of the arm 34. It is apparent that with the parts in the just described position, the sashes and 11 may be moved relative to each other since the portion 30 of the arm 31 will move through the portion 36 of the slot 25. However, when the portion 30 of the rod 31 is moved over into engaging relation with the portion 27 into the position depicted in Fig. 3 any relative move- Vment by the sashes 10 and 11 will tend to move the housing relative to the member n which will securely latch the 22 and thus the portion 2.7 will act on the arm 31 to tend to move said arm upwardly which will move the shoulders 32 thereof into engagement with the louter edge of the wall 26 ,sashes 10 and 11 so as to prevent further relative movement therebetween.v VIt will thus be seen that this device may expeditiously be Vuse-d so as to serve as a. latch for the window. The portion 27 will rest in therecess 33 iniorder that the arm 31 will be disposed substantially horizontal. The device also embodies another util-ity which. will now be set forth.

' l/Vhen the arm 31 is ydisposed in the'position depicted in F ig. 3 the arm 34 is moved across the slot 25 into a position such 'that it will be retained by the lug 35. The arm 31 may then Y be moved to a substantially vertical position and it will therefore be disposed in engagement with the arm34. However, should-the sashes'be moved relative to each other the arm 31will ride in the substantially cylindrical opening 29'.y It is therefore apparent that the sashes maybe moved `relative t-o each other' and that therod 31 will slide along inthis opening 29. In order to limit this relative movement, the rod '31' is made of a pre-de- V termined length and aball 38 is provided en the upper end. ofthis rod which is of greater sizel thanv the opening 29 and it is therefore apparent that when the ball 33 engages the wall 28, further movement between the sashes will be prevented. Figs. 4 and 5 serve to clearly depictrthis relative movement, Fig. 5 depicting the greatest movementl possible between the sashes 10 and V11 and showing the rod 31 in substantially vertical position. Fig.

otherwise mover the lsashes relative to each i other in a great amount, the section 30 is disposed in the portion 36 of the slot 25 and theV housing 20 and the portion 13 are pivoted about the -pintle 17 into the position depicted in dotted lines in Fig. 2 and when in this position it is apparent'that the sashes. may be moved in any desired `amount relative to each other and also Vthe appurtenances will be disposedV from position relative VVto 'the windowrpanes of the sash so as cleaning thereof. Y

`While I have illustrated and ydescribed the preferred form of construction for carrying my invention into effect, this is capable of variation and modification, lwithout departing from the spirit of the invention.V I, therefore, do not wish to be limited to the precise to facilitate details ofgconstruction setrforth, but desiretoy Y avail myself of such variations and modifications as come within the scope of the appended claims.
